Microsoft DirectX 9.0


The SetConeOrientation method sets the orientation of the sound projection cone.


HRESULT SetConeOrientation(
  D3DVALUE x, 
  D3DVALUE y, 
  D3DVALUE z, 
  DWORD dwApply 


x, y, and z

Values that specify the coordinates of the sound cone orientation vector. D3DVALUE is defined as float.


Value that specifies when the setting should be applied. This value must be one of the following:

Value Description
DS3D_DEFERRED Settings are not applied until the application calls the IDirectSound3DListener8::CommitDeferredSettings method. This allows the application to change several settings and generate a single recalculation.
DS3D_IMMEDIATE Settings are applied immediately, causing the system to recalculate the 3-D coordinates for all 3-D sound buffers.

Return Values

If the method succeeds, the return value is DS_OK.

If the method fails, the return value may be DSERR_INVALIDPARAM.


This method has no effect unless the cone angle and cone outside volume have also been set to values other than the default.
